Graphs That Represent A Function That Has An Inverse. For a function to have an inverse it must be one to one pass the horizontal line test. Analyzing graphs to determine if the inverse will be a function using the horizontal line test.
Which statement could be used to explain why f x 2x 3 has an inverse relation that is a function. Therefore the inverse is a function. Sketch the graphs of f x 2x2 and g x x 2 for x 0 and determine if they are inverse functions.
Now that we can find the inverse of a function we will explore the graphs of functions and their inverses.
Each of the toolkit functions has an inverse. Sketch both graphs on the same coordinate grid. Sketch the graphs of f x 2x2 and g x x 2 for x 0 and determine if they are inverse functions. Therefore the inverse is a function.
